[Solved] require/import/Npm.require() all return empty object

help
1

I’ve got an issue where installing @paypal/checkout-server-sdk via npm results in an empty object upon require(‘@paypal/checkout-server-sdk’) or import paypal from ‘@paypal/checkout-server-sdk’ or Npm.require(…).

If I create a test.js file in my project’s root directory and require() the package and run ‘node test.js’, I can print out the expected result just fine. Any ideas what might be happening here?

I’ve tried…:

  • deleting node_modules and doing ‘meteor npm install’
  • Running madge to find circular deps (found a few - e.g. jQuery - but didn’t see any that looked at all related)
  • Using import, require, Npm.require(). All result in empty objects.

I’m using Meteor v1.8.1 and the latest @paypal/checkout-server-sdk as of Sept 2019.

Any ideas of might be going on or what I might try next?

Thank you!

Very strange. I just spun up a new project to test and it’s working fine:

  1. meteor create paypal-import-test
  2. cd paypal-import-test
  3. meteor npm install @paypal/checkout-server-sdk
  4. Add import paypal from '@paypal/checkout-server-sdk' to server/main.js
  5. meteor run
  6. In a separate tab meteor shell
  7. Run require('@paypal/checkout-server-sdk') in the shell
  8. Which returns { core: {...}, orders: {...}, payments: {...} }

Can you post the code where you’re importing it and how you’re using it? It’s likely just a syntax error

Hey, thanks for taking the time…

So I’ve got it working now. Nothing changed in my code, but somehow I managed to do something with NPM to remove @paypal/checkout-server-sdk from package.json. I’ve looked carefully at my zsh history and git commits and it still isn’t clear to me what happened. But: it works now. Again, thank you for taking the time.

I’m wondering if I mixed ‘meteor npm’ with ‘npm’…nope, they’re both 6.9.0, so I suppose that shouldn’t matter.

I did have to do ‘meteor npm audit fix’, but that shouldn’t remove a package. Duno how it got removed. Anyway, thanks again!

Again with this!

I just installed a different NPM package and it’s requiring()/importing as an empty object.

All I did:

meteor npm i --save dropbox-v2-api

In my app:

import dropboxV2Api from ‘dropbox-v2-api’
console.log(dropboxV2Api)

Using require() yields the same result, which is {}.

Any thoughts?

I’ve tried doing ‘meteor npm install’ which does nothing. My package.json looks like this:

FIXED:

rm -rf node_modules
meteor npm install
<restart server>

This issue reappears erratically… Had the same with @material-ui/icons@4.9 but removing node_modules and reinstalling does not seem to be enough.
